Letters Patent No. 97 ,460,

dated November 30, 1869.

mrnovnn 'muse l v A The Schedule referred to in thse Letters Patent and making part of the same.

To alldvhom'it may concern l Figure I represents a view in perspective of my v improved truss;

Figure 2, a similar-'view ot the clasp which embraces. the hip-bone, detached; and

Figure, a view in elevation of that side of the pressure-pad next the clasp.

figure 4, a longitudinal central section through the pa The object of my invention is to provide a truss, simple in construction, eicientin operation, and comfortable tothe wearer; to which end,

My improvement consists in the combination of a metallic nonelastic clasp, encircling the ilium or hip-hone, only to hold the pad securely in place; a pad `possessing lastringent properties, to press `upon the. orifice ot' the hernia; and an elastic band, to secure the truss in place; the whole constructed as hereinafter fully set forth. j

The pressure-pad A is composed of some. metal. which will act as an' astringent and irritant upon the skin, such as lead, or a mixture of lead and tin, as I have found such action very beneficial.

l1`he pad is made .of a semi-oval form, and hollowed I out on its iiat side, to diminish its weight, and is secured fast tothe inner side of the arm b,of the clasp B.

This clasp is made of such length and shape as partially to enclose the hip-bone.

yielding to the movements of the wearer.

The clasp is covered by a belt of leather, or other `suitable fabric 'made in two sections, C C', united at the back by an elastic band or web, I), of any proper well-known material, and fastened .in front by a strap,

E, in the usual way, by means of a button, b', and a seriesr'of holes, e.

lIt will thus be seen, that hy mv invention, the pad, when once'tted to its place, is 1irxnly held, owing to the rigidity of the clasp, while the elasticity ot'fthe belt permits it to accommodate itself to the movements of the wearer.

I am aware that elastic clasps, elastic bands, and astringent pressure-pads are all old, and do not, therefore, claim them broadly per se; but I am not aware that a rigid clasp, an elastic band, and an astringent pad have ever been combined in a truss prior to my invention.

' What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the inelastic metal clasp, encirlcling the ilium only, the astringe-nt pressure-pad, and the elastic band, all these parts being constructed as set forth, for the purposes specied.
